Providing the app.d would be helpful, or at least a snippet of
it with the import that’s giving you the ‘error’—presumably a
compiler error?
No, I am just importing 'protobuf'.
Well, the package path is `google.protobuf`. If you import
`protobuf` then you are telling the compiler to import something
that does not exist, so naturally that gives you this error:
If you try to import protobuf in the app.d, it just wont work.
Here is that error.
source/app.d(2,8): Error: unable to read module `protobuf`
source/app.d(2,8): Expected 'protobuf.d' or
'protobuf/package.d' in one of the following import paths:
import path[0] = source/
import path[1] =
../../../../.dub/packages/protobuf/0.6.2/protobuf/src/
import path[2] = /usr/include/dlang/dmd
Error /usr/bin/dmd failed with exit code 1.
Also, I tried with both google.protobuf and just protobuf. Same
error.
So, how does this error look when you `import google.protobuf`?
dub is telling you the file path:
`../../../../.dub/packages/protobuf/0.6.2/protobuf/src/` ~
(`protobuf.d` or `protobuf/package.d`).
If you look, you will see that there’s no such file or folder,
but [there should be a google folder & a protobuf folder inside
it](https://github.com/dcarp/protobuf-d/blob/master/src/google/protobuf/package.d). The folder structure defines how the modules & packages are named (i.e. `google/protobuf/package.d` => `import google.protobuf`), so in the future you can check the folder structure if you have this issue anywhere else, since sometimes dub packages just don’t say how they should be imported.
Also the app is literally the base app when you run dub.init.
Here is a more exact error.
app.d(2): Error: unable to read module `protobuf`
app.d(2): Expected 'google/protobuf.d' or
'google/protobuf/package.d' in one of the following import
paths:
import path[0] = /usr/include/dlang/dmd
Are you just running dmd on `app.d` from inside `source` this
time? If not then why are all of your project’s import paths
missing??
Although I do remember I got something interesting when trying
to build a subproject of this one (it wasnt there for some
reason)
Did you try `dub build protobuf:protoc-gen-d`?
Uhh, just 'root'. Where my dub.sdl is?
Yes, that’s the root directory of your dub package.
